最近的一项全基因组关联研究将RELN的一个常见变异(Rs7341475G)与女性精神分裂症的风险联系起来。在迄今为止报道的最大规模的神经影像中间表型研究中,我们评估了rs7341475对一系列不同神经科学指标的影响。采用基于体素的形态计量学(VBM)和扩散张量成像(DTI)评价脑结构。用功能磁共振成像(FMRI)检测工作记忆过程中的脑功能。检测死后大鼠背外侧前额叶皮质和海马区脑组织中RELN的表达。共检查了736个数据集(VBM:230个,DTI:93个,fMRI:308个,RELN表达:105个)。我们的分析没有提供证据证明基因或性别交互作用对任何被检查的指标有显著的主效应。这项研究没有表明rs7341475对大脑结构、功能和RELN表达有重大影响,认为这种SNP和其他与之相关的SNP不会影响与精神分裂症生物学相关的大脑测量。
A recent genome-wide association study linked a common variant in RELN (rs7341475G) with risk for schizophrenia in women. In the largest neuroimaging intermediate phenotype study reported so far, we evaluated the effect of rs7341475 on an extended array of different neuroscientific measures. Brain structure was evaluated using voxel-based morphometry (VBM) and diffusion tensor imaging (DTI). Brain function during working memory was examined with functional magnetic resonance imaging (fMRI). RELN expression was determined in post-mortem brain tissue of the dorsolateral-prefrontal cortex and hippocampus. A total of 736 datasets were examined (VBM: n = 230, DTI: n = 93, fMRI: n = 308, RELN expression: n = 105). Our analyses did not provide evidence for a significant main effect of gene or gene by sex interaction effect on any of the examined measures. This study does not suggest a significant impact of rs7341475 on brain structure, function and RELN expression, arguing that this SNP and others linked with it do not affect brain measures related to the biology of schizophrenia.
